@benzinazero from the English version of the article:
"But what if we made electronically controlled cars? And if we placed them in a fixed line one behind the other? You know, like Tesla cars in Elon Musk’s Boring Company tunnel? The bad news is: Elon Musk cannot overcome the limitations of physics, also his tunnel is prone to traffic jams at high demand [Mor22]. The good news is: if you couple those electric vehicles together and make them run on a fixed schedule, say every 3 minutes, it works. But it has been around for ages and is called a subway or metro. A subway line routinely transports 25000 people/h. To get that many people to work by car, we would need a highway with 9 lanes toward the city – and 9 more lanes to leave the city again, a total of 18 lanes. A lane on a German highway [Bun09] has a width of 3.75m, so that would make (including emergency lanes) for a highway more than 70m wide. Imagine bulldozing such gigantic highways through our cities from all directions. Imagine the gigantic cost of construction, of resettling thousands of people, and of destroying cultural heritage and established economical structures. There is a reason why subways work better than highways for urban transportation. And the reason for that boils down to physical laws of acceleration and deceleration and mathematics, as you have learned."
